The objective of the BMU funded R&D project “Sol-ion” is to develop an integrated system which maximizes self consumption: Self produced PV power which exceeds simultaneous consumption is stored in an appropriate local storage medium and injected into the grid only, if power is needed. This paper presents the Sol-ion approach to develop a demand driven energy management system to make use of PV generated energy by storage, feed-in and self consumption in a single system. We will explain the concept and architecture of an integrated PV system with storage and first results from simulation and prototype testing and its market impact potential.
